    摘要: Provided is a computer system containing plural storage systems which manages the bandwidth of the storage systems in accordance with storage area attributes. The computer system is characterized in that: a control unit incorporates related file information in metadata, the related file information containing information for identifying a second file which to be write-accessed in conjunction with access to a first file by a client computer, and an access type of the write access. The control unit refers to the related file information to obtain the second file and the access type when the first file is accessed by the client computer. The control unit reads, from the obtained second file stored in the disk device, data corresponding to the obtained access type, to store the read data in a cache memory.

    摘要: A backup control apparatus references duplication management information comprising first stored location information indicating the stored location of a first information resource and second stored location information indicating the stored location of a second information resource which duplicates the first information resource, and identifies, from among a plurality of information resources belonging to a backup region, the first information resource stored in the location indicated by the first stored location information, and a second information resource stored in the location indicated by the second stored location information corresponding to the first stored location information. Then the backup control apparatus replaces the identified second information resource with linked information indicating a link to the identified first information resource, and backs up the backup region in which the second information resource is replaced with the linked information.

    摘要: A storage system 103 carries out first and second de-duplication processes in response to receiving a write request from a client. First, a determination is made as to whether a write target data item overlaps with any of the stored data items of a part of a stored data item group, which is a user data item group stored in a storage device 209, and if so, the write target data item is prevented from being stored in the storage device. Second, a determination is made as to whether a target stored data item, which is not finished being evaluated as to whether it overlaps with the stored data item in the first de-duplication process, overlaps with another stored data item, and if so, the target stored data item or the same data item overlapping with the target stored data item is deleted from the storage device 209.

    摘要: Files stored in a storage system are grouped in a metadata server, and storage servers discretely storing these files are instructed to detect file duplication and to remove duplicate data. The storage servers detect duplicate data by comparing file fragments stored by the storage servers themselves with each other. In a case where duplicate data is detected, the storage servers delete the duplicate data.
